I run SETI@home because it is a simple way of helping the cientific comunity in this project. After all we are ask ourselves if we are alone in the universe. The SETI program search for the answer.
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
